Regarding “convincing someone to buy your product is not that easy”, I do agree with you, but at the same time, I remember all those products I’ve bought online. I did not search on Google for those products neither I went to the company websites to get information and buy. They were affiliate people and their blogs that inspired to buy them. PrettyLink Pro, SEO Pressor was recommended by Kimberley, I bought Profits Theme, WP Zon builder because Alex Whaley recommended. Similarly I bought CommentLuv Premium because Ileane, Kavita, Steve and many others were talking good about it.

Let no one tell you that email marketing is dead. An email list is crucial for every affiliate marketer. You can start building up your email list with a lead magnet (like the information products mentioned previously) or even just by encouraging your audience to sign up for your updates. You can then push your content to this audience via email and also direct them to your affiliate offers. Don't be sleazy about the sales, but if you build up enough trust with your email audience; when the time comes, they will not mind purchasing a product from you. 
Great tips! Since I just started blogging in January I am still really just getting my toes wet in affiliates. However, I did notice that pictures and real life demonstrations of the product really help. For instance, I have several food posts where I talk about my favorite cook books and show what I have cooked out of them, and then included amazon links, sure enough I sold a few cook books.
When you promote a product you also promote the person or the company who is behind the product so try to choose wisely. You don’t want your visitors to go and buy a product following your advice then come back unhappy. Do you think that this visitor will come back to your site and take your advice again? Most likely no; this can hurt your credibility in the long run. Usually, websites/company that offer good customer service will have better customer satisfaction so try to stick with promoting their products.

Cookie stuffing involves placing an affiliate tracking cookie on a website visitor's computer without their knowledge, which will then generate revenue for the person doing the cookie stuffing. This not only generates fraudulent affiliate sales but also has the potential to overwrite other affiliates' cookies, essentially stealing their legitimately earned commissions.
Beyond these great offerings, Wealthy Affiliate doesn’t demand high upfront fees.

Will my target audience realistically spend this amount for the product? Again, your reputation is on the line here. Is the product you are thinking of promoting priced reasonably for your audience? When I was writing my ebook, I was stuck on pricing. I asked around for opinions. A number of people suggested I price my ebook at $47! Their idea was to price according to value, not size. In my mind that was crazy. My network was composed of a lot of stay-at-home bloggers, and my collective audience was comprised mostly of people without a whole lot of disposable income. There was no way anyone was going to pay $47 for my 30-page ebook.
But you should understand that you won’t become instantly rich by selling product. This type of business is highly competitive because there are many other people into it.

Once you've signed up, you'll be able to create unique links that allow the company to track them back to you so you get credit for the referrals you provide. It's important to read the fine print to know the limitations of how and where you're allowed to include the links because it varies from program to program. You can then start dropping these links into places where readers are likely to click on them and buy whatever is being advertised. These places include blog posts, newsletters, and Twitter and Facebook posts. (See also: How to Earn Extra Income With Twitter)
You can sell affiliate stuff if you did not use the stuff but a high, high, high, really high level of clarity is required to do this. Most bloggers lack this clarity. I recall Tony Robbins selling/being an affiliate for a $25K coaching class. Never took it. Never sat in it. But the guy made millions. He had full clarity in selling without seeing. So he rocked out the selling.
Some advertisers offer multi-tier programs that distribute commission into a hierarchical referral network of sign-ups and sub-partners. In practical terms, publisher "A" signs up to the program with an advertiser and gets rewarded for the agreed activity conducted by a referred visitor. If publisher "A" attracts publishers "B" and "C" to sign up for the same program using his sign-up code, all future activities performed by publishers "B" and "C" will result in additional commission (at a lower rate) for publisher "A".

WP Rich Snippets – premium plugin that adds rich snippets (eg. review stars) to your snippets. You get 33% of sales and it’s what I use on my site. However the developer does not provide plugin updates or support. Here’s a post I used it on. If you’re writing reviews, you 100% need SOME rich snippets plugin. The All In One Schema plugin works too and is free, but has minimal settings. If you want to allow users to submit reviews, try the Site Reviews plugin.
